File structure.

From SCF version 3.0 onwards the in memory structures and the data on the disk are not in the same format. The overview of the data on disk for the different versions is summarised below.


Versions 1 and 2

(Note Samples1 can be replaced by Samples2 as appropriate.)

Length in bytes                        Data
---------------------------------------------------------------------
128                                    header
Number of samples * 4 * sample size    Samples1 or Samples2 structure
Number of bases * 12                   Base structure
Comments size                          Comments
Private data size                      private data
